The skinny on Delphi's autonomous road trip across the United States [w/videos]

Rolling out of an S-shaped curve along Interstate 95, just past Philadelphia International Airport, the final obstacle between the autonomous car and its place in history appeared on the horizon. So far, the ordinary-looking SUV had traversed the United States without incident. It had gone through tunnels and under overpasses. It circled roundabouts and stopped for traffic lights. Now, on the last day of a scheduled nine-day journey, it was poised to become the first autonomous car ever to complete a coast-to-coast road trip. First, it needed to contend with the Girard Point Bridge. Riding in a rear seat, "I saw that bridge coming, and I thought, 'Oh my gosh, this is going to be a grab-the-wheel moment," said Kathy Winter, vice president of software at Delphi Automotive. The car, an unassuming Audi SQ5 nicknamed Roadrunner, had been well-tested. Back in January, a few inebriated pedestrians fell flat in front of the car during a demonstration in Las Vegas. It was the quintessential worst-case scenario, and the car admirably hit the brakes. More than drunken louts, bridges present a sophisticated challenge for the six radar sensors that feed data to the car's internal processors. Instead of sensing solid objects, radar sensors can read the alternating bursts of steel beams and empty space as conflicting information. "They're a radar engineer's worst nightmare," said Jeff Owens, Delphi's chief technology officer. Girard Point Bridge, a blue skeleton of girded steel that spans the Schuylkill River, might be a bigger challenge than most. Traveling across the lower level of its double decks, the autonomous car's radar sensors had to discern between two full sets of trusses. Cross the Schuylkill, and Delphi's engineers felt confident they'd reach their destination: the New York Auto Show. For now, the sternest test of the trip lay directly in front of them. A Data-Mining Adventure Until that point, the toughest part of the journey had been finding an open gas station in El Paso, TX. Trust in the technology had already been established. The main reason Delphi set out on the cross-country venture with a team of six certified drivers and two support vehicles was to capture reams of data. What better way to do that than dusting off the classic American road trip and dragging it into the 21st century? They did exactly that, capturing three terabytes worth of data across 3,400 miles and 15 states.

Subaru WRX STI vs. Audi S3 in compact AWD dustup

It's not every day that a Subaru and an Audi can be reasonably compared head-to-head; the two brands tend not to compete directly in their respective segments. However, the latest WRX STI and the S3 Sedan offer the perfect chance to find out if the working-class Scooby can beat its upper-crust competitor.
The UK's Auto Express gets behind the wheel of these two all-wheel drive performance sedans, or saloons as the Brits call them. Across the pond, both of them are rated at an identical 296 horsepower, but the Subaru edges out the Four Rings on torque. Like in the US, British buyers have to pay a little more to get the Audi, but it comes with a nicer interior and more brand cachet, if that means anything to you.
The video starts out with a fairly standard road test comparing the two of them back-to-back - all fairly subjective. But then Auto Express takes the trip to the drag strip, and the results there are much more conclusive. There's a definite winner when they cross the line, but you have to scroll down to see which of these turbocharged models with rallying heritage wins out.

166 MPGe diesel-electric Audi Q7 E-Tron Quattro gets real in Geneva

Despite some warnings that plug-in vehicles would not make a big impression in Geneva this year, the first big reveals from the Peace Capital are indeed PHEVs. For example, the diesel-electric Audi Q7 E-Tron Quattro, which right out of the gate comes at us with some impressive numbers: an all-electric range of 34 miles and the "potential" to hit 166 miles per gallon equivalent. Whatever scale Audi is rating the new Q7 PHEV on, 166 MPGe is a resounding success. As we might guess from the prototypes we've seen and hints we've had, the Q7 E-Tron Quattro is not some auto salon fantasy. The vehicle will go on sale at the end of this year, in the UK, at least. Availability in the rest of Europe and here in the US is likely but unspecified in the press materials we've seen so far. The real-world reality of the Q7 E-Tron Quattro means that specs like a 0-100 kilometers an hour (62 miles per hour) time of six seconds and a top speed of 225 kmh (139.8 mph), CO2 emissions of under 50 grams per kilometer and a total system torque output of 516.3 pound-feet should be ours to test in the not-too-distant future. This whole E-Tron program is turning out to be quite something. Who else is ready?

Making its world public debut at the Geneva Motor Show, the new Q7 e-tron quattro combines a frugal TDI engine with lithium-ion battery technology for a potential range of up to 876 miles and the ability to travel emission-free for over 34 miles on electric power alone, contributing to an official CO2 figure of less than 50 grams per kilometre. The Q7 e-tron quattro is the second Audi model with a powerful plug-in hybrid drive system.
